Clarifying Exchange 2003's Dependency on WINS
I had been labouring under the delusion that Windows and Exchange 2003 servers no longer need WINS, it seems that I was wrong. However, what I now believe is that Exchange 2003 does not absolutely need WINS. What various Exchange 2003 processes absolutely need is, NetBIOS name resolution. On simple networks, like mine, Exchange 2003 can resolve NetBIOS names simply by just broadcasting. Now I expect that you are ahead of me on why big networks still need WINS, because broadcasts are limited to the local subnet.
Let us consider a quote: 'Microsoft tries to make sure all programs work without NetBIOS, but this may only apply to future products.' From the Microsoft source knowledgebase article: PSS ID Number: 837391.
